Sentences with phrase «while aged mice»

It should be noted, however, that while a study on senescent cell ablation in genetically normal mice would provide at least some evidence on the effect of senescent cells (and their ablation) on promoting cancer, even such a study would likely show less effect than could be anticipated in a large mammal model, since even normally - aging mice rarely suffer metastatic disease to the extent of aging humans, as sheer primary tumor volume is generally sufficient to be fatal to mice.
